Polymer Modified Bitumen

Polyflex is a polymeric waterproofing membrane with centre core of 20 micron High Molecular High Density Polyethylene film coated on both sides with Polymer Modified Bitumen. The bitumen on both sides is further protected by a thermo fusible film.

• Good dimensional stability
• Enhanced resistance to chemicals
• Elongation exceeding 300 percent to absorb all structural movements
• High tensile strength and cold flexibility

Polyflex is ideal for rooftops, basements and terrace gardens.

• Clean the surface to make it smooth.
• Apply a coat of Bengal Primer @ 0.3 liters per sqm on the clean surface.
• This should be followed by a coat of hot applied Bengal Bitumen 85/25 @ 1.2 kg per sqm
• Lay and press Bengal Polyflex on the hot bitumen.
• A minimum overlap of 100 mm is recommended between the two rolls of membrane to be sealed with blown bitumen.
• Bengal Aquaflex is to be topped with screed or tiles as the case may be.

• High softening point and high penetration.
 
• High elongation.
• Flexibility at very low temperature.
